@izzythepush,
When will the Voyagers, which were launched in 1977, leave the outer reaches of the solar system?
The Oort cloud, or the Opik-Oort cloud, which is named after Jan Oort, is a spherical cloud that surrounds our solar system, a cloud of predominantly icy objects such as comets that are comprised of mainly hydrogen, oxygen=water, ammonia and methane, and extends up to about a light year from the sun and defines the cosmographical boundary of our Solar System and the region of the suns gravitational dominance.
Even traveling at 35,000 mph, the Voyager probes will need another 300 years just to reach the inner edge of the Oort Cloud — a large sphere of icy space rocks that begins a couple of thousand times farther from the Sun than Earth.
The Oort Cloud is the most distant region in our solar system, and it's jaw-droppingly far away, extending perhaps one-quarter to halfway from our Sun to the next star.
To appreciate the distance to the Oort Cloud, it’s helpful to set aside miles and kilometers and instead use the astronomical unit, or AU — a unit defined as the distance between Earth and the Sun, with 1 AU being roughly 93 million miles or 150 million kilometers.
For comparison, Pluto’s more elliptical orbit carries it between about 30 and 50 astronomical units from the Sun. The inner edge of the Oort Cloud, however, is thought to be located between 2,000 and 5,000 AU from the Sun, with the outer edge being located somewhere between 10,000 and 100,000 AU from the Sun.
If those distances are difficult to visualize, you can instead use time as your ruler. At its current speed of about a million miles a day, NASA's Voyager 1 spacecraft won't enter the Oort Cloud for about 300 years. And it won’t exit the outer edge of the bubble for maybe 30,000 years. (GET THE FACTS)
